Security-Enhanced Linux secures the staff_wine processes via flexible mandatory access control.
The staff_wine processes execute with the staff_wine_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep staff_wine_t
The staff_wine_t SELinux type can be entered via the user_home_t, wine_exec_t file types.
The default entrypoint paths for the staff_wine_t domain are the following:
/home/[^/]+/.+, /usr/bin/wine.*, /opt/teamviewer(/.*)?/bin/wine.*, /opt/google/picasa(/.*)?/bin/wdi, /opt/google/picasa(/.*)?/bin/wine.*, /opt/google/picasa(/.*)?/bin/msiexec, /opt/google/picasa(/.*)?/bin/notepad, /opt/google/picasa(/.*)?/bin/progman, /opt/google/picasa(/.*)?/bin/regedit, /opt/google/picasa(/.*)?/bin/regsvr32, /opt/google/picasa(/.*)?/Picasa3/.*exe, /opt/google/picasa(/.*)?/bin/uninstaller, /opt/cxoffice/bin/wine.*, /opt/picasa/wine/bin/wine.*, /usr/bin/msiexec, /usr/bin/notepad, /usr/bin/regedit, /usr/bin/regsvr32, /usr/bin/uninstaller, /home/[^/]+/cxoffice/bin/wine.+
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux staff_wine policy is very flexible allowing users to setup their staff_wine processes in as secure a method as possible.
The following process types are defined for staff_wine:
staff_wine_t
Note: semanage permissive -a staff_wine_t can be used to make the process type staff_wine_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.
setsebool -P kerberos_enabled 1
If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on the mmap_low_allowed boolean. Disabled by default.
setsebool -P mmap_low_allowed 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.
setsebool -P nscd_use_shm 1
If you want to allow users to connect to PostgreSQL, you must turn on the selinuxuser_postgresql_connect_enabled boolean. Disabled by default.
setsebool -P selinuxuser_postgresql_connect_enabled 1
If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.
setsebool -P use_nfs_home_dirs 1
If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.
setsebool -P use_samba_home_dirs 1
The SELinux process type staff_wine_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
